Die Construction meines Apparates bezweckt, den Uebelstand zu beseitigen, dafs das zum Schmieren des Compressorkolbens dienende Mineralöl oder Glycerin beim Passiren der Druckventile zum gröfsten Theil zerstäubt und dadurch der Betrieb der Kühlmaschine beeinträchtigt wird.The construction of my apparatus aims to remove the problem that Lubricate the compressor piston serving mineral oil or glycerin when passing the Pressure valves atomized for the most part and thereby impaired the operation of the cooling machine will.
Von den Ammoniakgasen ist der Oelstaub in keiner Weise als flüssiger Körper abzuscheiden; es ist daher die Einschaltung eines Absonderungs- oder Oelabscheidungsapparates erforderlich, in welchem die mit dem Ammoniakgas zusammen zu einer Flüssigkeit sich verdichtenden Oelnebel vorher abgeschieden werden, ehe sie mit demselben in die Verdampfröhren des Generators gelangen und dadurch den Effect der Maschine erheblich beeinträchtigen. Aus dem angeführten Grunde ist die Absonderung des Schmierkörpers von dem flüssigen Ammoniak, bevor dasselbe in die Verdampfröhre gelangt, von der gröfsten Wichtigkeit und wird von mir in folgender Weise erreicht:The oil dust can in no way be separated from the ammonia gases as a liquid body; it is therefore the involvement of a Separation or oil separation apparatus required in which the ammonia gas together to form a liquid condensing oil mist are deposited beforehand before they enter the evaporation tubes with the same of the generator and thereby considerably impair the effect of the machine. For the reason given, the lubricant must be separated from the liquid ammonia before it enters the evaporation tube is of the greatest importance and is used by me in the following Way achieved:
Ich verwende ein Mineralöl als flüssigen Körper zur Sperr- und Schmierflüssigkeit, und da es specifisch erheblich schwerer ist als wasserfreies Ammoniak, so sinkt es in dem unter dem Condensator C für das Ammoniak angebrachten Sammelgefäfs S zu Boden. In den letzteren ist das zu den Verdampfröhren des Generators führende Ableitungsrohr 6 in solcher Höhe angeordnet, dafs von dem verdichteten flüssigen OeI nichts in dieselben gelangen kann. Die Höhe der Oelflüssigkeit kann durch einen in der Zeichnung nicht angegebenen Oelstandapparat beobachtet werden.I use a mineral oil as a liquid body for the sealing and lubricating liquid, and since it is specifically considerably heavier than anhydrous ammonia, it sinks to the bottom in the collecting vessel S placed under the condenser C for the ammonia. In the latter the discharge pipe 6 leading to the evaporation pipes of the generator is arranged at such a height that nothing of the compressed liquid oil can get into them. The level of the oil liquid can be observed using an oil level apparatus not shown in the drawing.
Bei unregelmäfsig vor sich gehender Verdichtung der Oelnebel und dadurch entstehenden Schwankungen des Niveaus des Oeles würde dasselbe sogar in dem Gefäfs S in das Rohr 6 steigen, es ist daher ein zweites Gefäfs darunter angeordnet.In the event of an irregular compression of the oil mist and the resulting fluctuations in the level of the oil, the same would even rise in the vessel S into the pipe 6, and a second vessel is therefore arranged below it.
Aus dem Sammelgefäfs S führt das Rohr 2 durch einen Hahn in ein darunter befindliches Oelerhitzungsgefäfs H, in welchem das OeI mittelst hindurchgeführter Dampfschlange 7, 8 erwärmt -wird, nachdem nach Erfordernifs das in S angesammelte OeI abgelassen ist.From the collecting vessel S , the pipe 2 leads through a tap into an oil heating vessel H located below, in which the oil is heated by means of a steam coil 7, 8 passed through it, after the oil accumulated in S has been drained if necessary.
Aus dem Öelerhitzungsapparat H führt das Rohr 3 in ein zweites Oelsammelgefäfs R, welches mit dem im oberen Theil mündenden Rohr 5 mit der Saugleitung des Compressors communicirt.From the oil heating apparatus H the pipe 3 leads into a second oil collecting vessel R, which communicates with the pipe 5 opening in the upper part with the suction line of the compressor.
Durch das Ansaugen der Pumpe tritt das OeI vom Erhitzungsapparat H nach JR über, aber nur die durch das Erwärmen des Oeles frei werdenden, darin enthalten gewesenen Ammoniakgase treten durch das Saugrohr 5 in den Compressor und treten wieder ohne Verlust in den engeren Kreislauf der Maschine ein.When the pump is sucked in, the oil passes from the heating apparatus H to JR, but only the ammonia gases released by the heating of the oil and contained therein enter the compressor through the suction pipe 5 and re-enter the closer circuit of the machine without loss .
Ebenso wird auch das OeI in seinem Kreislauf zu seiner Bestimmung als Sperrflüssigkeit in die Sperrkammer der Stopfbüchse bezw. als Schmierflüssigkeit für die Compressorpumpen durch den Injectionshahn des Compressorcylinders mittelst des mit einem Hahn versehenen Rohres 4 zurückgeleitet.The OeI is likewise in its cycle BEZW for its determination as a barrier fluid in the barrier chamber of the stuffing box. as a lubricant for the compressor pumps through the injection valve of the compressor cylinder by means of the pipe 4 provided with a tap.
Bei allen Maschinen, bei welchen es darauf ankommt, die unter hohem Druck zerstäubten Oeltheile des Schmiermaterials zu sammeln und dem Reservoir zuzuführen, ist die AnordnungIn all machines where it matters, which atomize under high pressure Collecting oil parts of the lubricating material and supplying it to the reservoir is the order of the day
der communicirenden Gefäfse zu verwenden, für den Zweck der Abscheidung von dem flüssigen Ammoniak bezw. den Ammoniakgasen bei Kühlmaschinen erfüllt diese Neuerung allein den Zweck vollständig. Um das im Gefäfs S sich sammelnde OeI continuirlich abzuführen und damit einer unzulässigen Erhöhung des Niveaus automatisch vorzubeugen, anstatt das OeI von Zeit zu Zeit mittelst des Hahnes am Rohr 2 abzuführen,' ist die in' Fig. 2 dargestellte Modification des Apparatsystems angeordnet.to use the communicating vessels for the purpose of separating the liquid ammonia or With the ammonia gases in cooling machines, this innovation alone completely fulfills the purpose. The modification of the apparatus system shown in FIG. 2 is arranged in order to continuously discharge the oil that has collected in the vessel S and thus automatically prevent an inadmissible increase in the level, instead of discharging the oil from time to time by means of the tap on the pipe 2.
Aus dem Sammelgefäfs S tritt das OeI in ein Gefäfs O, welches einen Schwimmer enthält. Der Schwimmer wirkt auf ein am Boden befindliches Ventil, welches er öffnet, sobald genügend OeI in dem Gefäfs angesammelt ist, um es heben zu können.From the collecting vessel S the oil passes into a vessel O which contains a float. The float acts on a valve located on the bottom, which it opens as soon as enough oil has accumulated in the vessel to be able to lift it.
Durch das Ventil tritt das kalte OeI in: den Oelerhitzungsapparat H und von da nach R weiter, um wieder als Sperrflüssigkeit bezw. Schmiermittel für die Compressorpumpe zu dienen.The cold oil passes through the valve into : the oil heating apparatus H and from there to R , to be used again as a barrier fluid. To serve lubricant for the compressor pump.
